As worry begins to mount over President Barack Obama’s Jade Helm 15 exercises, Congress is beginning to take action on the controversial operation that many believe is a precursor to martial law.

Rep. Louis Gohmert, R-Texas, recently became the latest lawmaker to express grave doubt about the exercises, and he pointed out something much of the media hasn’t reported — namely, which states are supposed to be “hostile” territory during the exercise.

Gohmert said in a letter to his constituents that he was deeply troubled by the fact that the territory deemed “hostile” is all in Republican-leaning states.

“Over the past few weeks, my office has been inundated with calls referring to the Jade Helm 15 military exercise scheduled to take place between July 15 and September 15, 2015. This military practice has some concerned that the U.S. Army is preparing for modern-day martial law,” Gohmert said in the letter.

“Certainly, I can understand these concerns. When leaders within the current administration believe that major threats to the country include those who support the Constitution, are military veterans, or even ‘cling to guns or religion,’ patriotic Americans have reason to be concerned,” he explained.
